The closed furnace of smelting enterprises produces a large amount of surplus tail gas in the smelting process. After the tail gas is collected, cooled and purified, it can be used for combustion or internal combustion generator set to generate electricity. The ferroalloy tail gas mainly contains carbon monoxide and hydrogen, which needs to solve the problems of detonation and tempering when used for internal combustion generator set to generate electricity.

The industrial exhaust generator set is mainly developed for the gas with high carbon monoxide content. It is developed by new optimization and design on the foundation machine. The unit as a whole adopts modular design, distributing three modules of motor, engine and supercharging and cooling. The engine is placed in the middle, which is convenient for daily maintenance. Inlet and exhaust, and cooling water are concentrated at the free end, which is convenient for installation and layout of the power station.
engine adopts the shunt inlet double pressurization technology, which is specially developed for hydrogen-containing units. The structure is reliable and the operation is safe. The twin supercharger has been optimized and matched to provide efficient pressurization pressure for the engine and improve the operation power and efficiency of the unit.

1. Three-stage modular design |
The unit adopts three-stage modular design, gas engine, turbocharged intercooling and generator three-stage design, to improve the maintenance operation of the unit; |
The engine is in the middle of the unit, with less auxiliary equipment on both sides, which is convenient for daily maintenance. The air intake and exhaust are concentrated at the free end, which is convenient for the layout of the power station. The three modules are evenly distributed to make the unit more evenly distributed and easier to lift. |
2. Shunt air intake technology |
For the biomass gas containing hydrogen, methane value is low, the combustion speed is fast, the gas machine is easy to temper and detonation, the use of the branch inlet technology, reliable structure, compared with the multi-point electronic injection, mechanical injection, the control mechanism is simple and reliable; , completely avoid tempering |
3. Shunt pressurization technology |
Adopting the shunt pressurization technology, the unit has high operation safety, the gas does not need other auxiliary pressurization equipment, saves energy consumption, and realizes the low pressure gas inlet. |
